A rare nova explosion will soon be visible in the Earth’s nighttime sky, according to officials at NASA. The event, which could occur anytime between now and September, is creating a buzz within ...
Particles in the air scatter short-wavelength light (blue and green) through Rayleigh scattering much more strongly than longer-wavelength yellow and red light. Loosely, the term crepuscular rays is sometimes extended to the general phenomenon of rays of sunlight that appear to converge at a point in the sky, irrespective of time of day.
Nova Cygni is not expected to experience another explosion again. “I was a teenage astronomy geek about to start college and was outside on the night of August 29,” Cooke said.
Astronomers are expecting a “new star” to appear in the night sky anytime between now and September in a celestial event that has been years in the making, according to NASA.
Particles in the air scatter short wavelength light (blue and green) through Rayleigh scattering much more strongly than longer wavelength yellow and red light. Loosely, the term "crepuscular rays" is sometimes extended to the general phenomenon of rays of sunlight that appear to converge at a point in the sky, irrespective of time of day.
An inversion is also produced whenever radiation from the surface of the earth exceeds the amount of radiation received from the sun, which commonly occurs at night, or during the winter when the sun is very low in the sky. This effect is virtually confined to land regions as the ocean retains heat far longer.
The sun emits the largest solar flare of this 11-year cycle, as imaged by NASA's Solar Dynamics Observatory on October 3. NASA/SDO NASA says the sun is in the highly active "maximum phase" of its ...
The solar storms of May 2024 (also known as 2024 Mother's Day solar storm [1] or Gannon storm in memory of Jennifer Gannon, [2] a space weather physicist [3]) were a series of powerful solar storms with extreme solar flares and geomagnetic storm components that occurred from 10–13 May 2024 during solar cycle 25.
